adjusting a slit width of at least the first portion with the adjustable ribs;
sealing ends of the first and second head with packings defining at least a portion of an end of the slit;
forming a coating liquid curtain having an extent greater than a width of the web;
drawing the web through the curtain; and
supplying the coating liquid through at least a the second portion of the slit at a greater flow rate than through the first portion of the slit due to differences between respective widths between the first and second portions of the slit in a web moving direction.
5. The method in accordance with claim 4, wherein the second portion of the slit has a width greater than no less than twice the width of the first portion of the slit.
6. A curtain coater comprising:
a curtain head, formed by at least a first and second head body, having a slit structured and arranged such that a first portion of the slit supplies a coating liquid curtain at least onto a surface of a moving web;
positionably adjustable ribs coupled to respective first or second head bodies to variably define a width of at least the first portion of the slit;
at least a second portion of said slit being located outside of edges of the moving web and having a width in a direction of web movement greater than the width of the first portion of said slit; and
packings coupled to seal ends of the first and second head bodies and to define at least a portion of an end of the slit.
7. The curtain coater in accordance with claim 6, wherein the greater width of the second portion of the slit is no less than twice the width of the first portion of the slit.
8. The curtain coater in accordance with claim 6, wherein coating liquid is supplied to said slit under pressure.
9. The curtain coater in accordance with claim 6, wherein said curtain head is positioned above an upper surface of the web.
10. The curtain coater in accordance with claim 6, wherein at least end parts of said slit are wider in width than a remaining portion of said slit.
11. A curtain coater comprising:
a curtain head, formed by at least a first and second head body, having a slit structured and arranged such that a first portion of the slit defined at least in part by an adjustable rib coupled to one of the first and second head body supplies a coating liquid curtain at least across a surface of a moving web;
packings arranged to seal ends of the first and second head body and to define at least a portion of an end of the slit; and
said slit having a second portion structured to form at least a portion of the coating liquid curtain beyond the edges of the web at a greater flow rate than through the first portion of said slit due to differences between respective widths between the first and second portions of the slit in a web moving direction.
12. The curtain coating in accordance with claim 11, wherein the second portion of the slit is wider, in a web moving direction, than the first portion of the slit.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
